## Installation

[Download plug.vim](https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim)
and put it in the "autoload" directory.

<details>
<summary>Click to see the instructions</summary>

### Vim

#### Unix

```sh
curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
```

You can automate the process by putting the command in your Vim configuration
file as suggested [here][auto].

[auto]: https://github.com/junegunn/vim-plug/wiki/tips#automatic-installation

#### Windows (PowerShell)

```powershell
iwr -useb https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim |`
    ni $HOME/vimfiles/autoload/plug.vim -Force
```

### Neovim

#### Unix, Linux

```sh
sh -c 'curl -fLo "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/plug.vim --create-dirs \
       https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
```

#### Linux (Flatpak)

```sh
curl -fLo ~/.var/app/io.neovim.nvim/data/nvim/site/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
```

#### Windows (PowerShell)

```powershell
iwr -useb https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim |`
    ni "$(@($env:XDG_DATA_HOME, $env:LOCALAPPDATA)[$null -eq $env:XDG_DATA_HOME])/nvim-data/site/autoload/plug.vim" -Force
```

</details>

## Usage

Add a vim-plug section to your `~/.vimrc` (or `~/.config/nvim/init.vim` for Neovim)

1. Begin the section with `call plug#begin()`
1. List the plugins with `Plug` commands
1. End the section with `call plug#end()`

For example,

```vim
call plug#begin()

" List your plugins here
Plug 'tpope/vim-sensible'

call plug#end()
```

Reload the file or restart Vim, then you can,

* `:PlugInstall` to install the plugins
* `:PlugUpdate` to install or update the plugins
* `:PlugDiff` to review the changes from the last update
* `:PlugClean` to remove plugins no longer in the list

> [!NOTE]
> That's basically all you need to know to get started. The rest of the
> document is for advanced users who want to know more about the features and
> options.

> [!TIP]
> `plug#end()` automatically executes `filetype plugin indent on` and `syntax
> enable`. We believe this is a good default for most users, but if you don't
> want this behavior, you can revert the settings after the call.
>
> ```vim
> call plug#end()
> filetype indent off   " Disable file-type-specific indentation
> syntax off            " Disable syntax highlighting
> ```

### Getting Help

- See [tutorial] page to learn more about the basics of vim-plug
- See [tips] and [FAQ] pages for common problems and questions

[tutorial]: https://github.com/junegunn/vim-plug/wiki/tutorial
[tips]: https://github.com/junegunn/vim-plug/wiki/tips
[FAQ]: https://github.com/junegunn/vim-plug/wiki/faq

## Examples

The following examples demonstrate the additional features of vim-plug.

### Vim script example

```vim
call plug#begin()
" The default plugin directory will be as follows:
"   - Vim (Linux/macOS): '~/.vim/plugged'
"   - Vim (Windows): '~/vimfiles/plugged'
"   - Neovim (Linux/macOS/Windows): stdpath('data') . '/plugged'
" You can specify a custom plugin directory by passing it as the argument
"   - e.g. `call plug#begin('~/.vim/plugged')`
"   - Avoid using standard Vim directory names like 'plugin'

" Make sure you use single quotes

" Shorthand notation for GitHub; translates to https://github.com/junegunn/seoul256.vim.git
Plug 'junegunn/seoul256.vim'

" Any valid git URL is allowed
Plug 'https://github.com/junegunn/vim-easy-align.git'

" Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
Plug 'fatih/vim-go', { 'tag': '*' }

" Using a non-default branch
Plug 'neoclide/coc.nvim', { 'branch': 'release' }

" Use 'dir' option to install plugin in a non-default directory
Plug 'junegunn/fzf', { 'dir': '~/.fzf' }

" Post-update hook: run a shell command after installing or updating the plugin
Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }

" Post-update hook can be a lambda expression
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }

" If the vim plugin is in a subdirectory, use 'rtp' option to specify its path
Plug 'nsf/gocode', { 'rtp': 'vim' }

" On-demand loading: loaded when the specified command is executed
Plug 'preservim/nerdtree', { 'on': 'NERDTreeToggle' }

" On-demand loading: loaded when a file with a specific file type is opened
Plug 'tpope/vim-fireplace', { 'for': 'clojure' }

" Unmanaged plugin (manually installed and updated)
Plug '~/my-prototype-plugin'

" Call plug#end to update &runtimepath and initialize the plugin system.
" - It automatically executes `filetype plugin indent on` and `syntax enable`
call plug#end()
" You can revert the settings after the call like so:
"   filetype indent off   " Disable file-type-specific indentation
"   syntax off            " Disable syntax highlighting

" Color schemes should be loaded after plug#end().
" We prepend it with 'silent!' to ignore errors when it's not yet installed.
silent! colorscheme seoul256
```

### Lua example for Neovim

In Neovim, you can write your configuration in a Lua script file named
`init.lua`. The following code is the Lua script equivalent to the Vim script
example above.

```lua
local vim = vim
local Plug = vim.fn['plug#']

vim.call('plug#begin')

-- Shorthand notation for GitHub; translates to https://github.com/junegunn/seoul256.vim.git
Plug('junegunn/seoul256.vim')

-- Any valid git URL is allowed
Plug('https://github.com/junegunn/vim-easy-align.git')

-- Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
Plug('fatih/vim-go', { ['tag'] = '*' })

-- Using a non-default branch
Plug('neoclide/coc.nvim', { ['branch'] = 'release' })

-- Use 'dir' option to install plugin in a non-default directory
Plug('junegunn/fzf', { ['dir'] = '~/.fzf' })

-- Post-update hook: run a shell command after installing or updating the plugin
Plug('junegunn/fzf', { ['dir'] = '~/.fzf', ['do'] = './install --all' })

-- Post-update hook can be a lambda expression
Plug('junegunn/fzf', { ['do'] = function()
  vim.fn['fzf#install']()
end })

-- If the vim plugin is in a subdirectory, use 'rtp' option to specify its path
Plug('nsf/gocode', { ['rtp'] = 'vim' })

-- On-demand loading: loaded when the specified command is executed
Plug('preservim/nerdtree', { ['on'] = 'NERDTreeToggle' })

-- On-demand loading: loaded when a file with a specific file type is opened
Plug('tpope/vim-fireplace', { ['for'] = 'clojure' })

-- Unmanaged plugin (manually installed and updated)
Plug('~/my-prototype-plugin')

vim.call('plug#end')

-- Color schemes should be loaded after plug#end().
-- We prepend it with 'silent!' to ignore errors when it's not yet installed.
vim.cmd('silent! colorscheme seoul256')
```

## Keybindings

- `D` - `PlugDiff`
- `S` - `PlugStatus`
- `R` - Retry failed update or installation tasks
- `U` - Update plugins in the selected range
- `q` - Abort the running tasks or close the window
- `:PlugStatus`
    - `L` - Load plugin
- `:PlugDiff`
    - `X` - Revert the update

## Post-update hooks

There are some plugins that require extra steps after installation or update.
In that case, use the `do` option to describe the task to be performed.

```vim
Plug 'Shougo/vimproc.vim', { 'do': 'make' }
Plug 'ycm-core/YouCompleteMe', { 'do': './install.py' }
```

If the value starts with `:`, it will be recognized as a Vim command.

```vim
Plug 'fatih/vim-go', { 'do': ':GoInstallBinaries' }
```

To call a Vim function, you can pass a lambda expression like so:

```vim
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
```

If you need more control, you can pass a reference to a Vim function that
takes a dictionary argument.

```vim
function! BuildYCM(info)
  " info is a dictionary with 3 fields
  " - name:   name of the plugin
  " - status: 'installed', 'updated', or 'unchanged'
  " - force:  set on PlugInstall! or PlugUpdate!
  if a:info.status == 'installed' || a:info.force
    !./install.py
  endif
endfunction

Plug 'ycm-core/YouCompleteMe', { 'do': function('BuildYCM') }
```

A post-update hook is executed inside the directory of the plugin and only run
when the repository has changed, but you can force it to run unconditionally
with the bang-versions of the commands: `PlugInstall!` and `PlugUpdate!`.

> [!TIP]
> Make sure to escape BARs and double-quotes when you write the `do` option
> inline as they are mistakenly recognized as command separator or the start of
> the trailing comment.
>
> ```vim
> Plug 'junegunn/fzf', { 'do': 'yes \| ./install' }
> ```
>
> But you can avoid the escaping if you extract the inline specification using a
> variable (or any Vim script expression) as follows:
>
> ```vim
> let g:fzf_install = 'yes | ./install'
> Plug 'junegunn/fzf', { 'do': g:fzf_install }
> ```

### `PlugInstall!` and `PlugUpdate!`

The installer takes the following steps when installing/updating a plugin:

1. `git clone` or `git fetch` from its origin
2. Check out branch, tag, or commit and optionally `git merge` remote branch
3. If the plugin was updated (or installed for the first time)
    1. Update submodules
    2. Execute post-update hooks

The commands with the `!` suffix ensure that all steps are run unconditionally.

## On-demand loading of plugins

```vim
" NERD tree will be loaded on the first invocation of NERDTreeToggle command
Plug 'preservim/nerdtree', { 'on': 'NERDTreeToggle' }

" Multiple commands
Plug 'junegunn/vim-github-dashboard', { 'on': ['GHDashboard', 'GHActivity'] }

" Loaded when clojure file is opened
Plug 'tpope/vim-fireplace', { 'for': 'clojure' }

" Multiple file types
Plug 'kovisoft/paredit', { 'for': ['clojure', 'scheme'] }

" On-demand loading on both conditions
Plug 'junegunn/vader.vim',  { 'on': 'Vader', 'for': 'vader' }

" Code to execute when the plugin is lazily loaded on demand
Plug 'junegunn/goyo.vim', { 'for': 'markdown' }
autocmd! User goyo.vim echom 'Goyo is now loaded!'
```

> [!NOTE]
> #### Should I set up on-demand loading?
>

INSTALLATION                                                 *plug-installation*
==============================================================================

{Download plug.vim}{3} and put it in the "autoload" directory.

       {3} https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim


USAGE                                                               *plug-usage*
==============================================================================

Add a vim-plug section to your `~/.vimrc` (or `init.vim` for Neovim)

                                                           *plug#begin* *plug#end*

 1. Begin the section with `call plug#begin()`
 2. List the plugins with `Plug` commands
 3. End the section with `call plug#end()`

For example,
>
    call plug#begin()

    " List your plugins here
    Plug 'tpope/vim-sensible'

    call plug#end()
<
Reload the file or restart Vim, then you can,

                                            *:PlugInstall* *:PlugUpdate* *:PlugDiff*

 - `:PlugInstall` to install the plugins
 - `:PlugUpdate` to install or update the plugins
 - `:PlugDiff` to review the changes from the last update

[!NOTE] That's basically all you need to know to get started. The rest of the
document is for advanced users who want to know more about the features and
options.

==============================================================================

 - `D` - `PlugDiff`
 - `S` - `PlugStatus`
 - `R` - Retry failed update or installation tasks
 - `U` - Update plugins in the selected range
 - `q` - Close the window
 - `:PlugStatus`
   - `L` - Load plugin
 - `:PlugDiff`
   - `X` - Revert the update


POST-UPDATE HOOKS                                       *plug-post-update-hooks*
==============================================================================

There are some plugins that require extra steps after installation or update.
In that case, use the `do` option to describe the task to be performed.
>
    Plug 'Shougo/vimproc.vim', { 'do': 'make' }
    Plug 'ycm-core/YouCompleteMe', { 'do': './install.py' }
<
If the value starts with `:`, it will be recognized as a Vim command.
>
    Plug 'fatih/vim-go', { 'do': ':GoInstallBinaries' }
<
To call a Vim function, you can pass a lambda expression like so:
>
    Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
<
If you need more control, you can pass a reference to a Vim function that
takes a dictionary argument.
>
    function! BuildYCM(info)
      " info is a dictionary with 3 fields
      " - name:   name of the plugin
      " - status: 'installed', 'updated', or 'unchanged'
      " - force:  set on PlugInstall! or PlugUpdate!
      if a:info.status == 'installed' || a:info.force
        !./install.py
      endif
    endfunction

    Plug 'ycm-core/YouCompleteMe', { 'do': function('BuildYCM') }
<
A post-update hook is executed inside the directory of the plugin and only run
when the repository has changed, but you can force it to run unconditionally
with the bang-versions of the commands: `PlugInstall!` and `PlugUpdate!`.

[!TIP] Make sure to escape BARs and double-quotes when you write the `do`
option inline as they are mistakenly recognized as command separator or the
start of the trailing comment.
>
    Plug 'junegunn/fzf', { 'do': 'yes \| ./install' }
<
But you can avoid the escaping if you extract the inline specification using a
variable (or any Vim script expression) as follows:
>
    let g:fzf_install = 'yes | ./install'
    Plug 'junegunn/fzf', { 'do': g:fzf_install }
<

< PlugInstall! and PlugUpdate! >______________________________________________~
                                                    *pluginstall-and-plugupdate*

The installer takes the following steps when installing/updating a plugin:

 1. `git clone` or `git fetch` from its origin
 2. Check out branch, tag, or commit and optionally `git merge` remote branch
 3. If the plugin was updated (or installed for the first time)
   1. Update submodules
   2. Execute post-update hooks

The commands with the `!` suffix ensure that all steps are run
unconditionally.


ON-DEMAND LOADING OF PLUGINS                 *plug-on-demand-loading-of-plugins*
==============================================================================
>
    " NERD tree will be loaded on the first invocation of NERDTreeToggle command
    Plug 'preservim/nerdtree', { 'on': 'NERDTreeToggle' }

    " Multiple commands
    Plug 'junegunn/vim-github-dashboard', { 'on': ['GHDashboard', 'GHActivity'] }

    " Loaded when clojure file is opened
    Plug 'tpope/vim-fireplace', { 'for': 'clojure' }

    " Multiple file types
    Plug 'kovisoft/paredit', { 'for': ['clojure', 'scheme'] }

    " On-demand loading on both conditions
    Plug 'junegunn/vader.vim',  { 'on': 'Vader', 'for': 'vader' }

    " Code to execute when the plugin is lazily loaded on demand
    Plug 'junegunn/goyo.vim', { 'for': 'markdown' }
    autocmd! User goyo.vim echom 'Goyo is now loaded!'
<
[!NOTE] #### Should I set up on-demand loading?

You probably don't need to.

A properly implemented Vim plugin should already load lazily without any help
from a plugin manager (`:help autoload`). So there are few cases where these
options actually make much sense. Making a plugin load faster is the
responsibility of the plugin developer, not the user. If you find a plugin
that takes too long to load, consider opening an issue on the plugin's issue
tracker.

Let me give you a perspective. The time it takes to load a plugin is usually
less than 2 or 3ms on modern computers. So unless you use a very large number
of plugins, you are unlikely to save more than 50ms. If you have spent an hour
carefully setting up the options to shave off 50ms, you will have to start Vim
72,000 times just to break even. You should ask yourself if that's a good
investment of your time.

Make sure that you're tackling the right problem by breaking down the startup
time of Vim using `--startuptime`.
>
    vim --startuptime /tmp/log
<
On-demand loading should only be used as a last resort. It is basically a
hacky workaround and is not always guaranteed to work.

                                                                     *plug#load*

[!TIP] You can pass an empty list to `on` or `for` option to disable the
loading of the plugin. You can manually load the plugin using
`plug#load(NAMES...)` function.
